Og — Og ac 1.5ton asga18bmwa b r32 3 star

I purchased the product OG AC 1.5TON ASGA18BMWA B R32 3 STAR on 27/10/2021. On 24/06/23 we informed Authorised Servies Franchisee RJBREEZY ENTERPRISES that ac is not working. On 26/06/23 they said it is because of the gas leakage. They asked me to pay 4, 800 rupees. I asked for consideration because it not even 2yrs since I have purchased it. Till now I am not getting any proper response from them. I kindly request you give us a proper response
